Description
The output tetrode 6P1P-EV is used in the output single-cycle and push-pull circuits of low-frequency receivers and amplifiers. Designed to amplify low-frequency power in general-purpose radio-electronic equipment. Because of a different pinout (9-pin base versus 7-pin base) than an 6AQ5 / EL90, it cannot be used as a plug-in replacement for these types, however, it will work in the same circuit with component values unchanged, its maximum plate/screen voltage and dissipation ratings slightly higher than a 6AQ5.
Near equivalent tube: EL82, 6AQ5, EL90
E – characterizing the increased durability of the tube;
V – tube with increased reliability and mechanical strength.
